The Scotland trip follows Harry and Meghan's last engagement together, the Endeavour Awards in London, which marked their first formal evening event. In December, Prince Harry became colonel-in-chief of the Royal Marines.

Una Mallon, a mother of four, 47, from Belfast, said she thought Meghan would become "our new Diana".

Prince Harry and Meghan Markle met Scotland's First Minister at a reception to celebrate the achievements of young people in Edinburgh - and received an offer of a wedding band. Once inside the castle, they will observe the firing of the One O'Clock Gun - a tradition that started in 1861.
